Replica plating is a microbiological technique used to transfer colonies of microorganisms, such as bacteria or fungi, from one agar plate to another. This method is particularly valuable for studying genetic mutations, antibiotic resistance, or the effects of various environmental conditions on microbial growth. The basic procedure involves the following steps: 1. **Initial Culture:** A master plate is inoculated with microorganisms, allowing colonies to grow.
